UI Design

The design of what a user sees and operates — layout, type, colour, iconography and the visual states of every control.

Design Disciplines

UI design turns a defined structure into a usable surface: hierarchy that guides the eye to the primary action, spacing that groups related things, type that stays readable at real sizes, contrast that meets accessibility thresholds, and every state of every control specified. It is craft work with measurable constraints, not decoration.

It depends on UX design having answered what the screen is for. A beautifully executed interface for the wrong flow is still the wrong product, which is why the two are usually sequenced rather than merged — though on small teams the same designer does both, sometimes in the same afternoon.

In practice

A trading dashboard used the same weight and size for labels and values, so scanning a position took visible effort. Before: users reported the screen felt 'dense'. After dropping labels to a smaller, lighter treatment and raising numeric values, comprehension time in testing halved with no layout change. The catch — the flatter version had been chosen deliberately to look minimal.

Frequently Asked Questions

What is the difference between UI and UX design?

UX decides what the product should do and in what order; UI decides how that appears and behaves on screen. UX failures make a product useless, UI failures make it unpleasant or hard to read.

What accessibility basics should UI design cover?

Text contrast of at least 4.5:1 for body copy, visible focus states, touch targets around 44px, meaning never carried by colour alone, and text that survives being resized. These are baseline requirements, not enhancements.
